The retail server-directed-movement brain (0x00529010-0x0052a987),
Core-only with every App dependency as a ctor/property seam for the
V4/V5 cutovers: node-plan builders for all four movement types
(TurnToObject's desired-heading clobber quirk VERBATIM; TurnToHeading's
immediate BeginNextNode - ACE's one-tick-late gap not copied),
PerformMovement (cancel 0x36 + unstick first), BeginNextNode with the
sticky handoff order (radius/height/tlid read BEFORE CleanUp),
BeginMoveForward (GetCommand walk/run cascade + stored-params
write-back + progress-clock seed), HandleMoveToPosition (chase arrival
dist <= distance_to_object per the adjudicated BN inversion; fail
distance -> 0x3D; progress >= 0.25 units/s over >= 1 s, incremental AND
overall; fail_progress_count write-only - retail has NO give-up
threshold and none was invented), HandleTurnToHeading (20/340 aux
deadband; the Ghidra-confirmed heading_diff mirror), HandleUpdateTarget
0x0052a7d0 (deferred-start: object moves wait for the first Ok
callback; retargets reset the progress clock without requeueing),
UseTime's initialized gate, InitializeLocalVariables per retail (flags
word + context_id zeroed, floats stale, FLT_MAX resets - not ACE's
transpositions).
TDD catch: default(Quaternion) is the ZERO quaternion, not identity -
a fresh manager's heading computations would silently read 90 degrees;
explicit IdentityPosition resets match the decomp's identity-Frame
semantics. Also pinned: retail's explicit double adjust_motion in
_DoMotion/_StopMotion; entry points never drain pending_actions (only
PerformMovement's cancel does) - re-issues must route through
PerformMovement, documented + tested.
101 new conformance tests incl. three end-to-end scripted drives
(chase turn->run->walk-demote->arrive; flee; frozen-heading
TurnToObject through retarget). Full suite: 3,961 passed.
Implemented by a dedicated agent against the V0-pinned spec; scope +
suite independently verified.
